​

Answer 1

Answer:

25. The numbers are 4 and 5.

Step-by-step explanation:

Sum of 2 natural numbers:

4+5= 9

Sum of their reciprocal:

Reciprocal of 4= 1/4

Reciprocal of 5= 1/5

=1/4 + 1/5

=5+4/20

=9/20

Answer 2

Answer:

OR question length 16 and breadth 24

Step-by-step explanation:

The perimeter and area of a rectangular play ground are 80m and 384m².

perimeter = 2(l+b) = 80

area = l×b = 384

l+b = 40

take l×b = 384

16×24= 384

l = 16 and b= 24
